Well...I try very VERY hard to not jump to the spiritual side of dreaming. I'm like the Catholic church - it requires a lot to have me admit to something beyond the standard image subconscious world. That being said, that you don't normally dream so vividly (the term is actually lucidly), and that you and hubby both overslept...AND that the details given to you were SO specific (like the Starbucks visit)...well, I'd give serious thought to it having a spiritual visit. It's not the same context as having visions, just more like a way to interact with those you've lost. Today's date is within a month of all the dates you gave, so in part this is your mind relating to -all- of those dates as being close to the "now" point in time.

Dreams, unless a prophetic dream, which plays by a whole other set of rules, other dreams still relate back to how the subconscious mind works...and that has a LOT to do with archetypes and imagery...

In your dream, every character relates to you. Your mind is very self centered, and any character is usually a reflection of something you recognize within yourself. Some trait you see shared between you and your friend has brought them into mind. Same with your dad. Same with....every person in your dream, if you had the focus and time to investigate that deeply. I think the more interesting point for dream imagery is that you were at your mother in law's house. Usually a building represents the physical body - so the house would be you and every character within it is part of your own personality. But here we see that you are making a connection between you and your mother in law. Sooo, either you feel a sameness with her or you are feeling out of place in where you are. And crowded, that is very prevalent too. It shows when you say you don't know how all the people fit in such a tiny house. Thunder Bow seems to hit on something with a need for escape, as boiled down as it was... but I think there's more of that as a surface issue. Perhaps this feeling of being crowded is a diversion, hiding something deeper that's prodding at your subconscious.

Presuming there is some legitimate visit going on, the detailing of your Starbucks visit would be providing you proof of truth. Bottom line though si that your whole journey of the visit was re-connection. Is this something you're feeling like you're missing in life? Being surrounded by people, but you don't feel you're connected with any of them? Just a thought to consider.
